New solenoid model C. Valerio
New Field approach based on the QWT GPT include a solenoid model Two Solenoids are used to model the field Also, to improve the model the shape has been improved based On [1] Sol1 L= 0.1 m Sol2 L= 0.6 m For both the solenoid radius is set to 0.1 m B1/B2=20 [1]ILC Undulator-Based Positron Source with Quarter Wave Transformer at 250 GeV CM Energy Andriy Ushakov
GPT include a solenoid model Two Solenoids are used to model the previously used QWT Also, to improve the model the shape has been improved based On [1] Sol1 L= 0.1 m Sol2 L= 0.6 m For both the solenoid radius is set to 0.1 m B1/B2=20
Capture of efficiency volume acceptance Magnet strength scan from 0 to 8 Tesla Input beam Beam longitudinal uniform energy spread from 5 to 120 MeV The transversal energy spread is 20 MeV 2 cm aperture beam line The capture efficiency by energy depends on the magnet strength Energy histogram at the end of the line Z vs X (m)
Ratio between B1 and B2 effect B1/B2=20 B1/B2=10 Pz (MeV ) Pz (MeV )
Set of combinations We change The aperture, length and field magnitude of the second solenoid
Next steps Use the genetic algorithm to select one energy range and improve the capture efficiency in that region. 3 solenoids will be used to have more freedom in the shape of the field.
